find on its own. In return, the Mycorrhizae receive a protected environment and the sugars they need to thrive.
    Use of Mycorrhizae improves root depth, speeds maturation, and helps create resistance to drought and disease. Larger more robust root systems also improve the soil structure promoting better air and water movement.
    Flower Saver Plus should be used at plantingtime either as a root bath or worked into the top two to four inches of soil. Look for a product that has at least 50 to 100 spores per square foot.
    Seek medical attention if ingested. Avoid breathing the dust or spray, and keep out of reach of children.
Fulvic acid
    Fulvic acid is a naturally occurring organic substance resulting from the microbial action on decomposing plants. Absorbed into a plant, fulvic acid will remain in the tissues and serve as a powerful antioxidant as well as providing nutrients and acting as a bio-stimulant. Fulvic acid is an excellent source of nutrition for Mycorrhizae.
    Growers can create fulvic acid by composting or purchase the product from a retailer. It is available in forms suitable for hydroponics or soil mediums.
Gibberellins
    Gibberellic Acid (GA) is a natural plant growth hormone which acts with auxins to break dormancy, stimulate seed germination, and grow long stems.
    Gibberellic Acid can be purchased as a commercial product like Mega-Grow and is used to extend the grow season and force larger blooms. For best effect, use GA in complement with fertilizer and mixed into the water supply. Results can be seen in as little as a few weeks.
    According to the Material Safety Data Sheet (MSDS), GA is very hazardous to humans, and I do not advise using it; however, the retail advertisements claim the product is safe.
Humic acid
    Humic acids are carbons formed by the decomposition of organic substances, primarily that of vegetation. Applied to substrate, it encourages the creation of strong tissue growth and helps in nutrient transport. Plants grow thicker foliage and are more resistant to drought and disease.
    Poor soils can be improved by humic acid which enhances the water-holding capability and aeration in sandy soils and frees up nutrients bound in clay. It can be used as a root dip or sprayed directly onto the soil.
    Humic acids are extracted from humic substances found in soil. Colors range from yellow (fulvic acid) to brown (humic acid) and black (humin).
    Fulvic acid is the fraction of humic substances that is water soluble under all pH conditions. Fulvic acid stays in solution after humic acid dissipates due to acidification.
    Humin is the fraction of the soil organic matter that is not dissolved when the soil is treated with dilute alkali.
Hydrogen peroxide
    Hydrogen peroxide (H 2 O 2 ) is similar to water but carries an extra, unstable, oxygen molecule which can break down into a reactive atom and either attach itself to another oxygen atom or attack an organic molecule.
    Used in horticulture, hydrogen peroxide provides a host of benefits by cleansing water of harmful substances such as spores, dead organic material, and disease-causing organisms while preventing new infections from occurring. It removes the methane and organic sulfates often found in well water as well as removing chlorine from tap water.
    Hydrogen peroxide is especially useful in hydroponics, where overwatering can be a problem. It prevents oxygen depletion in the water around the roots, leading to better root growth. A solution of hydrogen peroxide can be used to sterilize seeds resulting in better germination rates.
    Hydrogen peroxide is dangerous at high concentrations (35%) and will damage skin, clothing, and most anything it contacts. Lower concentrations like those found at the drug store (3%) will still need to be diluted before use, though they are not as toxic to the gardener.
Indole 3 butyric acid (IBA)
    Indole 3 butyric acid is one of the auxin growth hormones. It is most often used as an effective rooting hormone. Application of IBA helps generate roots, build a larger root mass, and improve plant growth and yield.
    Many commercial formulas are available in the form of water-soluble salts. Cuttings can be dipped or immersed before planting. Roots can be dipped or sprayed or the soil drenched during transplanting. Once established, plantsshould be treated at three- to five-week intervals during the growing season. After harvest, IBA can be used to encourage regeneration of flowers.
    IBA is hazardous to humans and animals. It
